Abstract: A movement assistance device includes: a back plate that is fitted onto the back of a wearer; a back frame that has an elongated shape and is supported by a rotating shaft fixed to the back plate so as to be rotatable in a plane parallel to the back plate; a side frame that is rotatably supported by a rotating shaft fixed to the back frame and parallel to the longitudinal direction of the back frame and extends from the back frame toward the vicinity of the side waist of the wearer; a thigh holding portion that is fitted onto the anterior thigh of the wearer; and a drive portion that is connected to each of the side frame and the thigh holding portion and generates force that increases the angle between the side frame and the thigh holding portion.

Abstract: A movement assistance device includes: a hanging portion configured to be able to move a connecting end at least horizontally; a power assisted suit that assists a movement of an operator, and includes a fitting portion that is fitted onto an upper part of the torso of the operator, a pair of arm units that is provided along the arms of the operator from around the shoulders of the operator and generates supplementary power for assisting a movement of the arms of the operator following the movement, and a movement control portion that moves the hanging portion horizontally; and a suspension member that connects the connecting end of the hanging portion and the fitting portion of the power assisted suit and hangs the power assisted suit.

Abstract: A Faraday cage includes a casing structured by a first housing having a first outer cover made of a conductive material, and a first inner cover made of a conductive material, which is accommodated in the first outer cover and is electrically insulated from the first outer cover, and a second housing having a second outer cover made of a conductive material, which fits the first outer cover, and a second inner cover made of a conductive material, which is accommodated in the second outer cover and is electrically insulated from the second outer cover, the first and second housings being separable from each other; and a filter cartridge disposed inside the casing configured to be separable into two pieces, which accommodates therein a first filter for collecting fine particles sucked in from the outside the casing.
